When an item has been imported due to Thea’s automated ingestion, or when a user wants Thea to automatically discover media information for a manual download, Thea has very little known media information about the content - only what Metadata Scraping has provided.
By using what is already known about the item to perform a search on TMDB for matches, Thea can fill in the gaps in it’s media information (e.g. genre information, poster art, title, et cetera).
